Currently <strong>the</strong> average citizen of <strong>the</strong> Asia and Pacific region uses 1.6 global<br />

hectares (gha) of biologically productive land and sea (also known as<br />

biocapacity) to support <strong>the</strong> consumption of food, fiber, timber, energy and<br />

space for infrastructure and to absorb <strong>the</strong>ir carbon dioxide emissions,<br />

while only 0.9 gha is available. For most countries this gap is widening.<br />

Overall, <strong>the</strong> biocapacity available per person in 2008 was two thirds of that<br />

available in 1960. In a world of diminishing resources, this growing deficit<br />

can only be partially offset by imports of natural resources from outside<br />

<strong>the</strong> region. Strategies will be needed that result in more sustainable use of<br />

biocapacity and greater efficiency in use of resources. Without such<br />

measures, a growing deficit in <strong>the</strong> region will result in fur<strong>the</strong>r depletion of<br />

natural capital, loss of biodiversity, and loss of ecosystem services. For<br />

many of <strong>the</strong> rural poor, <strong>the</strong>ir access to natural capital is also at risk.<br />

The Ecological <strong>Footprint</strong> is an accounting framework developed by<br />

<strong>Global</strong> <strong>Footprint</strong> <strong>Network</strong> to measure <strong>the</strong> amount of biologically productive<br />

land and sea area that humanity needs to produce <strong>the</strong> resources it<br />

consumes, provide room for its infrastructure, and absorb its waste.<br />

The current National <strong>Footprint</strong> Accounts (<strong>Global</strong> <strong>Footprint</strong> <strong>Network</strong><br />

2011) track a resources ‘basket’ that includes crops, fish for food as well as<br />

o<strong>the</strong>r uses, timber, and grass used to feed livestock. It also includes<br />

productive areas that are being used for urban and transport<br />

infrastructure. Carbon dioxide from <strong>the</strong> burning of fossil fuel is <strong>the</strong> only<br />

waste product currently included in national <strong>Footprint</strong> assessments (Figure<br />

2). As people consume resources from around <strong>the</strong> world, <strong>the</strong> Ecological<br />

<strong>Footprint</strong> of consumption, measured in units called global hectares4 , adds<br />

<strong>the</strong>se areas toge<strong>the</strong>r regardless of where <strong>the</strong>y are located on <strong>the</strong> planet.<br />
